Step 1

Add pasta, broth, mustard, and garlic powder, to the inner pot of the pressure cooker. Stir to combine.

Step 2

Close the lid and set to sealing. Cook on manual high pressure 3 minutes. Wait for it to come to pressure. (It took my Instant Pot 5 minutes to reach pressure.) Using an oven mitt or towel, do a quick release and carefully open the lid so the steam escapes away from you.

Step 3

While hot, add the warm milk and shredded cheeses. Stir continuously until the cheese melts into a smooth creamy sauce. If there’s excessive liquid, saute the mixture for 3-5 minutes on normal heat.

Step 4

Stir in the spinach. Let sit for 5 minutes to thicken. Taste and add cracked black pepper to taste and salt if needed. Enjoy warm with a salad if you’d like even more veggies.
